Emergency Care Vocab
Health Occ
Laceration: a jagged, irregular tear of
the skin
Skin avulsion: tissue separates from
the body
Incision: a cut from a knife, glass, or
sharp rock
Puncture: a wound that tis caused by a
object piercing the skin
Abrasion: wound to outer layers of skin
that causes little bleeding
Poison: substance, solid, liquid or gas
that causes illness injury or death
when introduced to the body
First aid: the immediate temporary
care to a person that has become sick
or has been injured
Shock: failure of the system to keep
adequate blood circulating to the vital
organs of the body
Rabies: a disease of the nervous
system that could cause madness and
death
Sprain: stretching or tearing of
ligaments that hold bone together
1st degree burn: involves the top layer
of skin (sunburn)
2nd degree burn: involves the top layer,
skin will blister and appear blotchy
3rd degree burn: destroys all layers of
skin, nerves, muscle, fat and bones.
Burn looks brown or black
Fainting: a temporary loss of
consciousness, caused by reduced
blood supply to the brain
Frostbite: ice crystals form in the
spaces between the cells. Skin loses
color and become insensitive
Gangrene: Death of tissue, that comes
from frostbite that is untreated
Safety Guided notes
• Using book and the pages indicated in notes fill in guided notes
•
Stop after body mechanics
Body Mechanics:
• https://www.youtube.com/watch?v=uU41a1pgCIg
Body mechanics: Practice
• In lab stations practice perfectly good lifting body mechanics.
• Use the rubrics at station to make sure your partner hits all
the key steps
Microbiology:
• Using your books fill in guided notes up to the charts.

Types of Microorganisms: BACTERIA
• Most familiar microbe that
infects humans
• One celled plants classified
by their shape and
arrangement
• Strep throat, pneumonia,
TB, syphilis
• https://www.youtube.com/watc
h?v=kxM_9DL2GYw
Types of microorganisms: Fungi
• Lives on dead matter
• Ringworm, athlete’s foot, yeast
infection, thrush.
Types of microorganisms: Protozoa
These are freshwater single-celled microbes
that feed on bacteria and smaller protozoa.
• Tiny animals found in
contaminated water supplies
and in decayed material
• Malaria, trichomoniasis (STI),
dysentery
Types of microorganisms: Rickettsiae
Pronunciation:

• Parasites that must live inside
the cells of other living
organisms
• Transferred to humans by the
animal the parasite inhabits:
• Fleas, lice, ticks
• Humans bitten by an infected
insect may contract diseases such
as Rocky mountain spotted fever
Types of microorganisms: Viruses
• Smallest of all microorganisms
• See only with electron
microscope
• Need host cell to survive
• Spread through contact with
blood, body fluids
• Diseases: common cold,
chickenpox, herpes, HBV, AIDS…

Methods that Destroy microorganisms:
• Antiseptic:
• Solution on skin
• Alcohol or betadine used to clean skin
• Disinfection:
• Chemicals to kill pathogens
• Bleach
• Sterilization:
• Best way to kill all microbes
• steam
Standard precautions reading
• Please read the packet, answer the questions as you go in you packet
Principles of Infection
Key terms
Aseptic practices: used to keep an area free of
disease producing microorganisms
Medical Asepsis: “clean technique” , purpose
is to keep a clean environment so disease
won’t spread.
EX: hand washing, gloves
Surgical Asepsis: “sterile technique” a sterile
environment in which there are no
microorganisms or spores.
Transmission Precautions
Airborne Precautions:
disease that is spread by droplets in the air.
Must wear filter mask, and have negative pressure
in the room
Droplet Precautions:
Spread when someone sneezes or coughs
Should wear a mask
Contact Precautions
Could get transmission by contact or non contact
Have wound covered with sterile dressing at all
times
Infection only happens if the pathogens
alter the normal function of tissue.
They take up space and nutrients which
allows them to get bigger and stronger.
Chain of Infection
6 factors must be present for an
infection to occur.
If chain is never broken…NO infection
should occur!
Washing your hands will prevent the
spread of disease
= infection
= no infection
Infectious
Agent
Mostly harmless microorganisms
When they multiply they become harmful
They multiply in a reservoir. …
Reservoir
Reservoirs = humans, insects, food water,
bed linen or books
Pathogens stay in the reservoir until they
can escape
Portal of
Exit
Escape routes
Respiratory tract
Skin
Blood
GI tract
Mucous membranes
Mode of
Transmission
The way in which a pathogen goes from place
to place
Can be spread by direct contact or airborne
droplet
Proper hand washing is the best practice to
prevent transmission
Portal
of
Entry
 Pathogens need a portal of entry for transmission.
 Routes of entry:
Respiratory tract
Mucous membranes
GI tract
Cut on skin
Susceptible
Host
 One that is capable of becoming infected
Microorganisms must be present in large quantity
Host must be susceptible
If you are immune you are not susceptible
